Hi I am experiencing issue with 
UI
as it not showing any 
flows
and 
runs
. I register flow with success and see in agent logs and server logs that flow runs when is scheduled but I have no information about flows and runs in 
UI
.

Hi. I had the same situation when accessing the UI from another machine, then noticed in the browser's network activity requests to 
localhost:4200
. Worked around it by SSH-forwarding the 4200 port. I noticed an environment setting that might help in the compose file: https://github.com/PrefectHQ/prefect/blob/master/server/docker/docker-compose.yml#L90, will try to see if it does the trick.

Hi again @Bartek ! There's no need to port forward if you're on another machine; you'll just need to let Prefect Server know where the GraphQL API is deployed by setting the server graphql_url in 
~/.prefect/config.toml
like such:
Copy code
[server]
    [server.ui]
    graphql_url = "your_graphql_endpoint:4200/graphql"
Note, that's the 
config.toml
present on the machine you're deploying Prefect Server, and you'll need to restart the Server for changes to apply.

Hi @nicholas, thanks for the hint, that helped me as well. Browser requests now go to the Prefect server machine, however they're getting 
405
response codes.

Hm that's interesting, are the correct ports open (you'll need 4200 and 8080 unless you set up an external webserver)?
And you'll want to make sure your config endpoint ends with 
/graphql
, since that's the route GraphQL serves requests from
a
Yes, all the mapped ports are per the defaults.

@Andrei Duhnea are you able to post the full response you get in the UI from the server?
a
Hmm, I think I see what's wrong, it's using that config as a route to the UI endpoint:
Copy code
"POST /10.0.10.72:4200/graphql/ HTTP/1.1" 405 157 "<http://10.0.10.72:8080/>"
The request goes to 
<http://10.0.10.72:8080/10.0.10.72:4200/graphql/>
And my config has
Copy code
[server.ui]
graphql_url = "10.0.10.72:4200/graphql"
The full response is
Copy code
<html>
<head><title>405 Not Allowed</title></head>
<body>
<center><h1>405 Not Allowed</h1></center>
<hr><center>nginx/1.18.0</center>
</body>
</html>

Oh interesting, ok I think you need to add "http://" to the front of your 
graphql_url
a
yep, that was it
the missing scheme made it look like a relative path I guess
all good now
thank you
n
Great! Happy to help, this is good for me to know too, didn't realize that would be interpreted as a relative path without the protocol

thanks @nicholas @Andrei Duhnea

unfortunately I still cannot see any flows and runs in my UI. I have check path to 
graphql
and it works but in UI still no info about flows and runs
the url was correctly changed according to logs
n
@Bartek are you able to successfully call 
flow.register()
?
b
Yes
n
Hm interesting. If you're able to successfully register flows, that tells me the 
graphql_url
variable set in 
~/.prefect/config.toml
is incorrect for some reason. Can you share what you've got there?
b
Sorry @nicholas it works now. Probably I did something wrong previously. Thanks again 🙂
n
No worries at all, glad you got it figured out @Bartek!
